About PerfoMetrix

PerfoMetrix is a website health scanner. Enter an address and you get one report covering three things site owners usually check with three different tools:

• Performance: Core Web Vitals and Lighthouse lab data from Google PageSpeed Insights, plus real-user data from the Chrome UX Report when available.
• Security: HTTPS and certificates, security headers, cookie flags, email DNS records, known-vulnerable JavaScript libraries and Google Web Risk status.
• SEO: titles, descriptions, headings, canonical tags, structured data, robots.txt and sitemaps.

Every finding comes with a short explanation and a concrete fix, and our guides go into detail.

Passive by design

We only look at what any visitor can see. The scanner loads the page you submit and a few public files, at most 12 requests per scan. It never probes, guesses paths or attacks anything. Read more about our bot, including how to opt out.

Your data

Reports are private links that expire, and we store IP addresses only as daily one-way hashes. See the privacy policy.
